While in Japan my Mac suddenly stopped working. I noticed that my Magsafe light wasn't indicating any charged nor charging light was on checked my battery since I had previous problems with batteries and noticed it was pretty much dead low, however it was functional and in good shape. Puzzled I go to of my co-workers who has another Magsafe charger and plugged it in, nothing.
At that point I checked the Magsafe and notice some damage and came in conclusion it was that it had to be replaced. A quick visit to ifixit.com showed me the part as the left I/O board.
Tokyo has some nice stores but after 2-3 hours searching Akihabara (electronic city) no one had anything. I ordered the part from ifixit.com and only used my iPad and Samsung Infuse as my connections to the world.
A day after my arrival from Tokyo to Texas the part arrives and the fun begins.
I've replaced my Hard drives before so opening up my Mac was easy and despite that the manual itself said difficult, as long as you're AWARE of the many cables and wires you pull out from the board, it was quite easy. When I took the I/O board I immediately knew I made the right call, the mag safe was smashed and really damaged. Repairs took only 40-45 minutes tops.
When done I plug my Mac and SUCCESS!! I get light and charging left it overnight turned it on and checked that the audio and the ports that I/O board has were working properly. They did. It was well worth the wait and effort.
Make sure you plug in ALL cables and wires back to the boards. It be a pain to have to open up again and find where you left something out
Replaced Left I/O Board. The previous board's MagSafe connector had scorch marks on it.
It went fairly well except I have no sound! I probably just didn't get some of the connectors seated probably which I will check out in the next few days. However, I did wind up with an a dark gray wire with a black connector that I wasn't sure where it plugged in to. It was running with the AirPort Extreme wires. There was no mention of it in the instructions nor could I find any information on it on-line. Other than that, the replacement instructions were excellent and very accurate.
Just make sure everything is seated properly before you put the case screws back in!
